Part of the Union of Poles members, including Viktar Bohdan, decided to support the authorities. The criminal case was continued several times, the four activists were not allowed to leave the country. Later the proceedings were suspended.

Now the criminal case is reopened. Soon the four suspected activists would start receiving summons from investigator of the regional police department.
